Hi everyone, I ran across a great article in the current (April,2001) Mathematics Teacher from NCTM about the challenges andinstructional stategies for teaching and learning mathematicalsymbolism. While it is written for secondary teachers, I think it'sof value to upper elementary math teachers, too. Some of POWdiscussions have concerned the connection between reading and writingto communicate mathematical ideas, and math vocabulary andexplanations that demand precise mathematical language and symbols, so this article comes at a good time. I hope others find it helpful.
